This paper develops a two-country model of trade and factor mobility,
in which capital is sector-specific but internationally mobile. The mo
del avoids the indeterminacy and propensity to specialize of Heckscher
-Ohlin models and exhibits a rich variety of responses to exogenous sh
ocks, including transfers, capital taxes, and tariffs. The results thr
ow light on the relationship between goods and factor trade, reconcili
ng the conflicting views of previous writers. It is argued that the mo
del holds out the possibility of a new paradigm in international trade
theory in which international factor movements play a central rather
than a peripheral role.
